What does the 'Downstream V' represent in swiftwater rescue?

• A. Change in water temperature
• B. A formation of downstream water flow into channels of least resistance
• C. A marking of shallow areas
• D. An indicator of high water speed

Answer: (B)

The 'Downstream V' represents the formation of downstream water flow into channels of least resistance, which is critical in swiftwater rescue situations. When observing this V-shape, rescuers can identify areas where the water is converging. This can often indicate the path of least resistance for both the water and any potential victims caught in the current. Understanding this formation allows rescuers to anticipate flow patterns and make informed decisions during rescues, as it shows where the water is moving faster and where it may be safer to navigate. Recognizing the dynamics of the downstream V is essential for effective situational awareness in swiftwater environments, helping guide rescue efforts and strategy.
